SCAFFOLD-BRACKET.

SPECIFICATION forming part of Letters Patent No. 565,293, dated August4, 1896.

Application filed December 12,1895. fierial No. 571,882. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES MORGAN, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain new and usefulImprovements in Scaffold-Brack= ets, of which the following is aspecification.

This invention has for its object to provide a scaffold-bracket havingsimple and efficient means whereby the bracket may be securely locked toa vertical stud or beam and held locked by its own weight and the weightof its load.

The invention consists in the improvements which I will now proceed todescribe and claim.

0f the accompanying drawings, forming a part of this specification,Figure 1 represents a perspective view of my improved bracket, its hooksbeing shown in the position they occupy before attachment to a stud.Fig. 2 represents a side view. Fig. 3 represents a top plan view showingthe hooks engaged with a stud. Fig. 4 represents a section on the line 4A of Fig. 2.

. The same letters of reference indicate the same parts in all thefigures.

In the drawings, a represents a carpenters scaffold-bracket, which maybe of the usual or any suitable general form and construction.

I) I) represent two hooks, the inner ends of which are formed into eyesI) 12, adapted to swing loosely upon a bolt 0, passed through the arm ofthe bracket. The outer ends of the hooks project rearwardly from thebracket and are provided with inwardly-projecting spurs Z2 b adapted topenetrate opposite sides of a vertical stud or beam cl.

e e represent inclined guides affixed to the bracket and preferablyforming parts of a stout metal casting, the shank e of which is boltedor secured to the upright of the bracket, said guides being located atopposite sides of the bracket and separated from the upright by spaces,through which the hooks b b extend. I

The guides are inclinedinwardly from their lower to their upper ends, sothat when the hooks are raised or swung upwardly they will be at thesame time forced inwardly by the guides. V

The hooks normally rest at the lower ends of the guides e c, as shown inFig. 1, the spurs being at the greatest possible distance apart. Whenthe bracket is to be connected with a stud d, the upright of the bracketis placed against the front of the stud, thehooks standing at the sidesthereof. The hooks are then raised by hand until the spurs are incontact with the sides of the stud, and the bracket is then forceddownwardly, causing the guides to force the spurs into the stud, asshown in Fig. 3. The bracket is thus firmly locked to the stud andcannot be released excepting by being moved upwardly. Hence the weightof the bracket and its load tend to increase the firmness of theconnection.

To insure the spreading of the hooks when they drop to the lower ends ofthe guides, I provide the bracket with spreading-guides ff, which, ashere shown, are bent rods having their ends driven into the sides of theupright of the bracket, their lower portions being inclined and arrangedto bear on the inner sides of the hooks, so that when the hooks swingdownwardly they are deflected outwardly.

I claim- 1. A scaffold bracket having pivoted rearwarclly projectingstud-engaging hooks, and inclined guides arranged to force said hooksinwardly when they are raised.

2. A scaffold-bracket having pivoted rearwardly-projecting stud-engaginghooks, inclined guides arranged to force said hooks inwardly when theyare being raised, and inclined guides arranged to force the hooksoutwardly when they are being depressed.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 5th day of December, A. D.1895.
